Spring Constructor Injection Weird Error

I have encountered below BeanDefinitionDecorator error at below constructor-arg dependency line in Bean XML (root-context.xml) in Eclipse, but no issue when using setter injection with property element, appreciate if anyone here could provide advice, as not able to identify the root cause even after search through Internet. Thanks in advance.

Error encountered

"Multiple annotations found at this line:

• Cannot locate BeanDefinitionDecorator for element [constructor-arg]

• cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'constructor-arg'.

• Configuration problem: Cannot locate BeanDefinitionDecorator for element [constructor-arg] Offending resource: file [C:/Users/Administrator/ workspace/EsmProject/src/main/webapp/WEB-INF/spring/root-context.xml]"
